Summary
Acoustic rhinometry provides objective nasal cavity measurements. Decongestion significantly increased minimal cross-sectional area and volumes in healthy Macedonian adults, particularly in anterior and middle nasal regions.
Area of Science:
- Otolaryngology
- Medical Imaging
- Rhinology
Background:
- Acoustic rhinometry (AR) objectively measures nasal cavity geometry.
- No normative AR data exists for healthy adults in Macedonia.
- Establishing baseline data is crucial for clinical interpretation.
Purpose of the Study:
- To establish normal acoustic rhinometry values for healthy Macedonian adults.
- To evaluate nasal cavity changes following decongestion using AR.
- To assess the efficacy of nasal decongestion on nasal airflow dynamics.
Main Methods:
- 50 males and 50 females (19-40 years) underwent AR measurements.
- Key parameters measured included minimal cross-sectional areas (MCA1, MCA2) and volumes (V03, V25, V47, V07).
- Measurements were taken before and after nasal decongestion.
Main Results:
- Normative data for MCA1, MCA2, and nasal volumes were established for both sexes.
- Nasal decongestion led to statistically significant increases in MCA1, MCA2, and all measured volumes (p<0.001).
- The effects of decongestion were pronounced in the anterior and middle nasal cavity.
Conclusions:
- Acoustic rhinometry is a practical tool for nasal cavity assessment.
- Nasal decongestion significantly improves nasal cavity dimensions.
- The anterior and middle turbinate regions show the greatest response to decongestion.

01:15Respiratory Volumes
Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.

01:24Nose and Nasal Cavity
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
